Check PI naming conventions, plugin for flake8

Project description

Check the PEP-8 naming conventions.

This module provides a plugin for flake8, the Python code checker.

(It replaces the plugin flint-naming for the flint checker.)


You can install, upgrade, uninstall pep8-naming with these commands:

$ pip install pi-naming
$ pip install --upgrade pi-naming
$ pip uninstall pi-naming

Plugin for Flake8

When both flake8 and pep8-naming are installed, the plugin is available in flake8:

$ flake8 --version
2.0 (pep8: 1.4.3, pyflakes: 0.6.1, naming: 0.2)

By default the plugin is enabled.

These error codes are emitted:

class names should use CapWords convention


function name should be lowercase


argument name should be lowercase


first argument of a classmethod should be named ‘cls’


first argument of a method should be named ‘self’
